He says it's a 2spd automatic. Is this right??!!? I could've sworn that the only thing they had (speaking about the powerglides of 60-66) were 3spd autos? Anybody know for sure?

By the way, I can't be wrong either. | | | | | Joined: Aug 2004 Posts: 52 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2004 Posts: 52 | Powerglide is a two-speed. As far as I know, the TH-350 was the first GM 3-speed auto.
1946 GMC 1/2 ton
1967 Chevy 1/2 ton
This old truck sure looks neat, but where are the heated seat controls?!?

There are differences in the emergency brake cables to work with the re-positioning of the cross-member to accept the Th350 mount. Maybe this will help.

(well, not in my car)
From what I understand they are virtually indestructable. Some of you have already heard the story of my 62 chevy II with powerglide, got slammed into reverse at 40mph by my girlfriend. Car came to a screaming stop and stalled. Started right back up and drove perfectly.

Have one sitting in the shop corner also. popcorn The Truth is Out There (Life is way to busy for me)Ben | | | | | Joined: Oct 2004 Posts: 175 Member | | Member Joined: Oct 2004 Posts: 175 | powerglide, got slammed into reverse at 40mph When I was a youngster we used to do that at 60 mph just for kicks and grins. A 65 Impala will go completely sideways while screeching to a rather dramatic stop!  !

Thanks...my girlfriend says she "bumped" her VW from Drive to Reverse going down the highway, (riiiighhht) then got scared and slammed it back into drive - nothings wrong with it now!
Thanks again! | | | | | Joined: Jun 2000 Posts: 2,773 'Bolter | | 'Bolter Joined: Jun 2000 Posts: 2,773 | I can't agree that powerglides are nearly indestructible. Had one in a 63 Bel Air with a 300 hp 327. Around 120K miles it had been rebuilt twice, the first time with upgrades such as extra clutch discs. The second time was after the tranny slipped while I was driving down the road at 120 mph. After I rebuilt it I found I had blown a headgasket and ended up cracking the block. Sold it as fast as the old man would let me. My info came from http://www.novak-adapt.com/knowledge/transmission_gateway.htm
